What is a Standard-Essential Patent?

Understanding SEPs—patents essential to technology standards, FRAND licensing obligations, and their strategic importance.

Definition

A standard-essential patent (SEP) is a patent that claims technology required to implement a technical standard (e.g., 5G, WiFi, HEVC). SEP owners typically must license these patents on FRAND terms.

How SEPs Work

  1. Standards bodies (3GPP, IEEE, ETSI) develop technical standards
  2. Companies contribute technology that may become part of the standard
  3. If contributed technology becomes mandatory, related patents become "essential"
  4. Patent owners declare their SEPs and commit to FRAND licensing

FRAND Licensing

FRAND stands for Fair, Reasonable, and Non-Discriminatory. SEP owners must:

  • Offer licenses to anyone who wants one
  • Charge reasonable rates
  • Not discriminate between licensees in similar situations

Why SEPs Matter

  • For implementers: You must license SEPs to sell standard-compliant products
  • For patent owners: SEPs can be very valuable but come with licensing obligations
  • For the industry: SEPs balance innovation incentives with technology access

Challenges with SEPs

  • Over-declaration: Many declared SEPs may not actually be essential
  • Rate disputes: Disagreements about what FRAND rates should be
  • Hold-up/hold-out: Strategic behavior by both licensors and licensees
  • Essentiality assessment: Determining if a patent is truly essential is complex

What is the difference between a declared SEP and an essential SEP?

A declared SEP is one the owner has claimed is essential. Not all declared SEPs are actually essential—studies show 20-50% may not be. Essentiality must be assessed through claim-to-standard mapping.

What happens if you don't license SEPs?

Implementing a standard without licensing required SEPs constitutes patent infringement. SEP owners can seek injunctions and damages, though courts consider FRAND obligations.

How are FRAND rates determined?

FRAND rates are determined through negotiation, guided by factors like comparable licenses, portfolio quality, standard contribution, and the value the technology adds.
